[FF] Pasting content from Word causes problems

Description

When pasting content from a Word document that happens to have a date field the content styles are displayed incorrectly. The height of the text is incorrect and results in excessive overlapping (see attached example).

Also, the table in the provided word document is removed.

The incorrect font styles and the removed table issue only occur in FF. IE is working well.

To reproduce:

Open a nightly sample

Copy the whole contents of the Test_doc_with_date.doc

Use paste from Word dialog to paste the whole contents with default settings

Using the same document with the date field removed fixes the style issue (see Test_doc_without_date.doc), although the table is still removed.
